EARTH SCRAPER OR LEVELER.

SPECIFICATION forming part of Letters Patent No. 370,077, datedSeptember 20, 1887.

Application filed June 16, 1887. Serial No. 241,548. (No model.)

To @ZZ whom it may concern:

Be it known that I, CORNELIUS J. MINARD, a citizen of the United States,residing at Maquon, in the county of Knox and State of Illinois, haveinvented a new and useful Improvement in Earth Scrapers or Levelers, ofwhich the following is a specification.

My invention relates to improvements i earth Scrapers or levelers; andit consists in a certain novel construction and arrangement of parts,fully set forth hereinafter, and specitic-v ally pointed out in theappended claims.

.In the drawings, Figure lis a perspective View of my scraper. Fig. 2 isa detail side view thereof. Referring by letter to the drawings, Adesignates the body of the scraper, comprising the blade or cutter B andthe foot-board or platform O for the driver, and the said cutter isprovided at the sides with the rearwardly-extending ears b Z).

D designates a lever bifurcated at the lower end and having the rolleror caster Ejournaled in the said bifurcated end, and the said lever ispivoted some distance above the said caster on studsff, which are formedon the sides of the rear end of the arched bar F, which is pivoted nearthe rear end ou the ear b. G designates a curved arm or segment which 1ssecured to the bar F and passes through a sleeve, g, on the lever D, andthe said sleeve is adapted to operate ou the said curved arm when thelever is turned around on its pivot. The upper side ofthe arm G isprovided with ratchet-teeth, and I-I is a springpawl secured to andoperating with the lever D, which is adapted to engage in the saidratchet-teeth to hold the lever at the proper angular adjust ment.

It will be seen that by operating the levers D the cuttenblade will beeither raised or lowered, and thus it is adjusted to the desired height.

The draft-beams or tongues are attached to the front ends of the archedbars F, and the driver stands on the platform C to direct thedraft-animals and adjust the cutter, as described.

l, straining of the machine.

It will be seen that as the bar F is pivoted to the body of the cutterany desired sheer ofthe said cutter may be had by simply driving the lhorses attached to one of the tongues ahead of the others, andin case,by accident, one of the teams of horses does not pull as fast as theother, or pulls irregularly, there will be no As the rollers are in therear of the cutter, as seen, they are on the level to which the road isbeing reduced, and consequently by adjusting the levers any desiredamount of cnt may be made.

In cutters or levelers where the supportingwheels are on the sides ofthe machine any irregularities of the road will affect the depth ofthecut ofthe cutter; but in my device, where the supporting-wheels are inrear of the cutter,or on the part of the road which has been cut down,the depth of the cut will be always the same, or, rather, the road inrear of the cutter will be regularly cut.

The parts of the device are very simple and the means of adjustmenteasily operated, and therefore the machine will be found of greatutility and advantage.

Having thus described the construction, operation. and advantages of myinvention, I claiml. A scraper or leveler having the body A, comprisingthe cutter B and the platform O, ears b b on the sides of the body,arched bars F, pivoted to the said ears, curved arms G, attached to thebars F and having ratchetteeth on the upper side, levers pivoted to therear ends of the bars F and bifnrcated at the lower ends, rollers E,mounted in the said bifurcated ends, sleeves g to receive and operate onthe said toothed arms, spring pawls H to engage normally in theratchet-teeth on the said toothed arms, and the draftbeams or tonguessecured tothe said bars F, all constructed and arranged substantially asand for the purpose set forth.

2. A scraper or leveler comprising the cutter or blade B, having at eachend the draftbars F, the rollers or wheels E, and the elevating devicesconnected to the draft-bars to elevate the cutter B, as set forth. i

8. A scraper comprising the straight blade or cutter B, the platform Oin rear of the blade, the draft-bars F at each side of the blade andconnected to the same, and the elevating de vices connected to thedraft-bars.

In testimony that I claim the foregoing as my own I have hereto afxed mysignature in presence of two Witnesses.

CORNELIUS J. MINARD.
